Introduction. Vehicular trauma is one of the most common causes of canine trauma — at least 51% of the total number of the canine trauma according to the foreign statistics. The main risk group consists of the dog males aged from 1 to 3 years old. In Russia no research was conducted to analyse the prevalence of vehicular trauma in dogs that would allow determining the risk factors, the nature and severity of injuries, and making recommendations for the owners and veterinarians. This article proposes a retrospective evaluation of the vehicular trauma prevalence in dogs based on the data of the Rostov region veterinary clinic chain for the period of 2018–2022.Materials and Methods. For retrospective evaluation, the medical histories of patients of the “VitaVet” LLC veterinary clinic chain (Rostov region) were used as the material. The selection of medical histories was carried out from September 2022 to March 2023 in accordance with the following inclusion criteria: the presence of a vehicular trauma in the animal's anamnesis; diagnosis based on the physical examination, X-ray examination and ultrasound examination; absence of data on the other potentially life-threatening diseases in the animal medical history. The severity of dogs’ condition was evaluated according to five parameters of the ATT scale (Animal Trauma Triage) and the estimate shock index.Results. A retrospective evaluation of the vehicular trauma prevalence in dogs was carried out based on the data of 559 selected medical histories. Of these, 217 histories belonged to bitches (94% non-neutered) and 342 to dog males (98% non-neutered). It was revealed that the number of deaths in bitches was almost two times less in comparison with the male dogs (13% and 20.2% respectively). About 45% of vehicular trauma occurred in animals aged from 1 to 3 years old. The lowest percentage of deaths (6.15%) and the average ATT score (3.15±0.09) were found in bitches under one year old. In bitches aged from 1 to 3 years old, these parameters equalled to 10.74% mortality and 3.46±0.07 ATT score. Among male dogs, the lowest mortality percentage was found in males from 7 to 10 years old (11.11%), in animals under one year old it was 12.84%. The largest number of injured dogs was in the small dog breeds (63.69%), however in large dog breeds the percentage of deaths and the average ATT score were higher (54.8% and 4.34±0.3). The most common diagnoses resulting from the vehicular trauma were: femoral fracture, pelvic fracture, craniocerebral trauma, contusion, tibia fracture, vertebral fracture.Discussion and Conclusion. The results of the retrospective evaluation indicate that the young non-neutered dog males were most often subject to the vehicular trauma (dogs under the age of 3 years old were in the risk group). Mortality among the dog males was higher than among the bitches. The small dog breeds were more likely to get the vehicular trauma, whereas the percentage of deaths in large dog breeds was higher. The most common injuries observed during the period of research were the musculoskeletal disorders, this fully corresponds to the data published in the foreign scientific sources. Further expansion of the sample of research taking into account the data of the other veterinary clinic chains will create the opportunity for getting a more detailed picture in the research area.
